Geosynthetic clay liner Introduction
It is betonite geo-synthetic waterproofing barrier. It is self-attaching and self -sealing to concrete or other construction structures. It is made of a non-woven geotextile, a natural sodic bentonite layer, with or without a pe geomembrane layer, and a polypropylene sheet.
These layers are connected with a dense felter that makes the bentonite a self-confinement with controlled expansion. With this system it is possible to avoid slippage and the accumulation of bentonite as a consequence of cuts, tears, vertical applications and movements.
Its performance can meet or exceed GRI-GCL3 and our national standard JG/T193-2006.

Functions
The engineering function of a GCL is containment as a hydraulic barrier to water, leachate or other liquids and sometimes gases. As such, they are used as replacements for either compacted clay liners or geomembranes, or they are used in a composite manner to augment the more traditional liner materials. The ultimate in liner security is probably a three component composite geomembrane/geosynthetic clay liner/compacted clay liner which has seen use as a landfill liner on many occasions.
